The last thing you probably do when a fly buzzes toward you is marvel at its graceful wing and body kinematics. But that’s exactly what researchers at Cornell University’s Itai Cohen Group...

Briefs: Mechanical & Fluid Systems

Between walking and running, human gaits can cover a wide range of speeds; for example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog....

Briefs: Medical

A new type of mechanical instrument was developed to perform complex, minimally invasive procedures, also known as laparoscopic surgery. The technology could lead to less trauma for...

Fine-grained human motion tracing — the ability to trace the trajectory of a moving human hand or leg, or even the whole body — is a general capability that is useful in a wide variety of...

Briefs: Communications

A paper-thin, flexible device was created that can generate energy from human motion, and can act as a loudspeaker and microphone. The transducer is ultrathin, flexible, scalable, and...

Heading Versus Tilt Chart for Assessing HGA Occlusion and Flop Risk in MSL Operations

The Mars Science Laboratory (MSL) high-gain antenna (HGA) sits low on the deck, leaving the sky occluded in many directions by other parts of the rover. Each drive must end with the rover at a heading where the Earth will be unoccluded during the next HGA...

EXOS Software

An improved version of EXOS software allows for the modeling of fabrics, mixtures, and porous materials, and also provides the ability to accept hex mesh geometries. The code employs a novel numerical method, a hybrid particle finite element approach, as well as particles and elements in tandem, each modeling distinct aspects of...
